4 Claims. 1

This invention relates to locking devices and, more particularly, to the type of locks known as combination locks.

One object of the invention is to provide a lock of this nature which is adapted for use in looking, windows, cupboard doors and many other articles of this nature, wherein it is desired that the article locked cannot be readily opened by anyone without knowing the locking combination.

Another object of the invention is the provision of a lock of this nature which cannot be forced and one which is highly jimmy-proof.

Another object is to produce a device of this nature in which the maximum simplicity of construction and operation is secured.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and co-relation of parts herein fully described, and illustrated in the accompanying drawings, wherein similar refer ence characters'are used to describe corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to be understood from an illustrative, rather than a restrictive standpoint.

In carrying out the present inventive concept it has been found advantageous to provide a block or keeper having an extending bar or pin by which it may be securely positioned adjacent the parts to be locked. The keeper is further provided with a hole or opening having a knob or projection which is adapted to be progressively engaged by annular and longitudinal slots or grooves in a locking pin or bolt, the said grooves being so arranged that it is necessary to turn the locking pin from one position to another in order that the said pin may finally enter alined holes in the parts to be locked.

It was further found advantageous to provide the locking pin or key with blind grooves in withdrawing direotion, which when engaged by the projection in the keeper will prevent withdrawal of the key and the consequent unlocking of the parts.

In the accompanying drawings:

Figure 1 is a front elevational view of a portion of two sliding halves of a window, showing the keeper in place with the locking pin removed therefrom;

Figure 2 is a sectional view taken on line 22 against unwarranted opening by means of a block or keeper M which has at one side thereof a projecting bar, rod, or pin 15, which may be either rectangular, triangular or square in cross section and which may be securely driven into a hole or opening lGa in the window frame l2.

The keeper block I4 has a hole is extending the entire thickness thereof, the said hole being in alinement with a pair of alined holes I7 and E8 in the lower and upper window sashes H and I0, respectively. Located in the keeper block hole It and near the front face of the said keeper block is a knob or projection IS. The circumference of the hole [6 .may be dividedinto any suitable number of divisions, as, for instance, eight as illustrated in Figure 1. The said divisions are numbered from 1 to 8 inclockwise direction.

The window sashes may be locked together by means of a key or locking pin Zll comprising a head 2!, a shank 22 having aplurality of annular grooves 23 and longitudinal grooves or slots 24. The slots 24 are out of alinement with each other, the innerly disposed ones open into and connect the transverse or annular slots 23.

To look the window sashes against sliding movement the key is inserted into the hole it with the foremost groove 24 in engagement with the projection IS, the key is slid inwardly until the projection I 9 engages the first annular groove 23, the key is then rotated and simultaneously pressed inwardly until the projection i9 enters the second longitudinal slot 2 This operation is repeated until the last slot 24 engages the projection l9, at which time the reduced pin portion 25 is fully seated in the window sash openings IT and I8, and the window is locked.

In the present instance the locking and opening combination is 1, 4, 5, 1. To obtain this combination the key is rotated clockwise or counterclockwise until the index line 26 on the head 2| progressively coincides with the numerals 1, 4, 5, and l on the indicia dial 21.

may be had with the numbers indicated and with the number of longitudinal slots employed... 7

It will be understood that the number of dial divisions as well as the number or-key .diVi'SiQIlS': and longitudinal grooves may beincreased or 4 connected by staggered axial grooves, said grooves being adapted to engage the projection in the keeper opening when the key is operated for looking and unlocking movement, the shank being further provided with blind grooves adapted to be engaged by the keeper projection when the key is operated in unlocking direction to hinder the unlocking operation for those unfamiliar with the lock combi'natiommeans on the key adapted tobe brought into registry with the dial for freely operating the key in'locking and unlocking direction, and a projection on the shank to engage the alined sash openings and lock the window.

.3. In..a look, a keeper having a hole therein, a

projection in said hole, a key therefor, said key comprising 'a shank adapted to rotatably fit said hole and having annular spaced apart otherwise varied so that the permutation may-be 7 very great. 7

It will further be understood that the lock may be used in a great many difierent ways and forv locking objects other than windows and the like. 7

It is apparent that' the illustration shown above has been given by Way of illustration and not by way of limitation and that the above .example is subject to wide variations and modifications, without departing from the scope or intent of the present invention; All of such variations and modifications are to be included Withinthe- .2.
